Unable to change the scheduled scan timings

Hi,
I have symantec endpoint protection 11.x setup in my system. By default a daily scan and a weekly scan are configured at a point of time during day which slows down my system drastically. When I try to edit both, I get error message saying "This is a read-only scan. It cannnot be edited." My administrators have tried and given up.

I tried to update the policy by right clicking on task bar over the Symantec protection icon.. it showed "requesting updated policy from symantec endpoint protection manager" and disappeared. Nothing happened after that.

Hello Deva_pdy
Is your client comminicate with your sep manager? you should be sure client take new policy.
you can try this;
create a test group and create new antivirus and antispy policy. and move this client new group and update content.
than check client take this policy and moved new group
(open client interface click help and support choice trobleshooting. you can see group in there)
Thanks

Where you are trying to change the scan schedule in SEPM or in client side?
If a scan is configured in SEPM we can change it in SEPM only
For this you can edit the antivirus and antispyware policy
Come to administrator defined scans select the scan which you want to change, click on edit go to the schedule tab here you will get an option for changing the timing
Also ensure that the user which u logged in to SEPM having the right to change those settings....

Hi All,
Thanks for your suggestions. My client is taking the policies from SEPM for sure. I was able to change the schedule time by hacking the registry (though I knew it's not advisable). Whenever windows reboots or when the policy is updated by selecting update policy, timings get back to default values. This shows, my scan configuration is defined in SEPM and not in client.

I will check with my administrator to change the policy in SEPM as suggested.

This is assuming that your clients are managed. You need to edit the scan and then assign this changed policy to the group of desired clients. Be sure to check the policy serial number on the SEPM as well as the Client so that you know that the client has the correct policy.
